The object of the present invention is to suitably control a charging state of a human body all the time. A charging amount detection deviceis worn by a human body and measures the surface potential of the human body. A static electricity control deviceis worn by a human body and generates and discharges ions to the human body and thereby controls the static electricity on the human body. A mobile terminalsets a control pattern of the static electricity on the human body that is suitable for a condition such as temperature and humidity for the static electricity control devicevia short-range wireless communication. The static electricity control deviceuses the set control pattern to perform feedback control of the static electricity on the human body by using the surface potential of the human body measured by the charging amount detection device

An apparatus for manufacturing an element array includes a substrate hold means, a laser radiation device, and a collection mechanism. The substrate hold means holds a substrate including an adhesive layer on which elements are attached in a predetermined array while a surface of the adhesive layer is inclined relative to a horizontal surface at a predetermined angle. The laser radiation device radiates a laser to a specific element among the elements attached on the adhesive layer. The collection mechanism is disposed below the substrate and configured to receive the specific element falling by the laser radiation.

Apparatus for manufacturing element array and apparatus for removing specific element

In a method of manufacturing an element array, prepared is an adhesive sheet in which elements are arranged in a predetermined array on an adhesive layer. A specific element among the arrayed elements is removed from the adhesive sheet by radiating a laser to the specific element. The arrayed elements are directly or indirectly transferred onto a mounting substrate.

Method of manufacturing element array and method of removing specific element

An observation apparatus is provided. An apex angle of a contact prism is inputted by operating an apex angle setting knob of a control panel. A fining angle of the contact prism is inputted by operating a fitting angle setting knob. A control unit determines the amount of correction for astigmatism of a left observation optical system and the amount of correction for astigmatism of a right observation optical system based on a recognized observation magnification and the inputted apex angle. An axial angle for the astigmatism of the left observation optical system and an axial angle for the astigmatism of the right observation optical system are determined based on the inputted fitting angle. Variable cross cylinder lens rotating drive units are controlled to rotate cylinder lenses of each of the right and left observation optical systems, thereby obtaining the determined axial angle and the determined amount of correction.

An optometric apparatusaccording to the present invention comprises a body portionprovided with an optical system for a right eye for projecting a chart for the right eye in order to inspect visual function of both eye of an examinee and a body portionprovided with an optical system for a left eye for projecting a chart for the left eye, the optical systems for the right and left eyes projecting the same fusion patterns to perform fusion of the both eyes of the examinee.

Ophthalmologic apparatus and ophthalmologic chart

In an optometric apparatus of the present invention, optometric apparatus bodiesandindependently driven in right-and-left and up-and-down directions for optometry of an examinee, respectively, are provided on both sides of a face receiving device

Optometric device

Disclosed is a subjective optometric apparatus in which the earpiece members and the nose pad member for attaching the main body of the device to the subject can be easily adjusted without involving any effort. The subjective optometric apparatus has a horizontal frame and an inner tube inserted into the horizontal frame, with a support bar for supporting a nose pad member being passed through the horizontal frame and the inner tube. In a state in which the inner tube is being biased by a spring, a rubber member provided in a through-hole of the inner tube abuts the peripheral surface of the support bar to lock the support bar, thereby bringing the nose pad member into a locked state. Further, when a push-button is pushed in against the biasing force of the spring, the inner tube is displaced and the rubber member is detached from the peripheral surface of the support bar, with the result that the nose pad member is released from the locked state and becomes capable of being displaced.

Subjective optometric apparatus

An optometry apparatus of the present invention comprises an optical element provided in a correction optical system , which has a spherical lens and a cylindrical lens and which corrects examined eyes E to be subjected to optometry, wherein the optical element is used so that targets are seen as if they were dispersed in a plane orthogonal to an optical axis O and shown simultaneously at a different distance or position in a direction of an optical axis through the eyes E to be subjected to optometry.
